Plain-English Terms for Small Trade Jobs: The Ten Lines Worth Putting in Writing

Writing clear terms for small trade jobs doesn't mean a long legal document; ten plain lines on the quote will head off most arguments.

Ask a tradesperson what causes most arguments with customers and you'll hear a familiar list. "They said it was included." "I thought you'd be done by Friday." "Nobody told me I'd have to pay for the parts." "I didn't know you'd charge for coming back."

Notice that none of these are about bad workmanship. They're about expectations. Two people held two different pictures of the same job, and nobody checked until it was too late.

The usual cure is a written agreement, and that's where many small traders come unstuck. A long page of legal text feels heavy, unfriendly and expensive to produce. So they use nothing, and rely on goodwill and a handshake, which works right up until it doesn't.

There's a middle path. This guide sets out ten plain-English lines worth putting in writing for small trade jobs, in words an ordinary customer will actually read. You'll also learn why short beats long, where to put the lines so people notice them, and how to know when a job is big enough to need proper advice. It is general guidance, not legal advice, and the rules differ by country, so treat it as a starting point.

Why a short, readable agreement beats a long one nobody reads

It seems logical that more detail means more protection. In practice, a long document often protects you less.

Customers don't read it. A wall of small print is skimmed at best, and a customer who didn't read it can feel ambushed when you rely on it.

It can feel hostile. A heavy legal tone signals mistrust, which can sour a friendly job before it begins.

It may not fit the job. Standard text copied from elsewhere may not match what you do, or may include things you don't actually intend to enforce.

It's hard to apply consistently. If you don't remember what's in it, you can't apply it fairly.

In many places, rules also require terms to be clear and fair, and unfair or hidden terms may not be enforceable. Check the official guidance where you work.

A short, plain, visible set of lines does better. The customer reads it. You remember it. It sets expectations without frightening anyone.

Think of it as a conversation written down. Each line should answer a question the customer might ask: how much, when, what's included, what happens if something changes.

If you wouldn't be comfortable saying it aloud to a customer's face, think again about whether it belongs in the document.

The ten lines, in plain words

Here are ten lines that cover most of what causes trouble. Adapt each to your trade and your country, and keep them in your own voice.

1. What you're doing. "We will supply and fit one mixer tap in the kitchen, remove the old tap and test for leaks."

A clear description of the job. It is the foundation for everything else.

2. What's not included. "This price does not include making good decoration or tiling."

It's better to say it now than argue about it later.

3. The price. "The price for this work is $X, [including / excluding] tax."

State the amount and whether tax is included. If it's an estimate rather than a fixed price, say so.

4. How changes are handled. "If the work turns out to need something different from what we've quoted, we'll tell you before going ahead and agree any change in price."

This protects both sides. Our guide to handling job variations and extras explains how to do it smoothly.

5. When and how payment is due. "Payment is due on completion. We accept [methods]."

Or, for larger jobs: "A booking payment of $X is due to secure the dates, with the balance due on completion."

6. What happens if payment is late. "If payment is late, we may charge [what applies]."

Check carefully what you are allowed to charge, because rules on late payment and fees differ by country and customer type. Many small traders simply state when payment is due and leave it at that.

7. When the work will happen. "We expect to attend on [date] between [time] and [time]. If we need to move the date, we will let you know as early as we can."

Realistic expectations are better than hopeful promises.

8. What you need from the customer. "Please make sure we can get to the work area and that water and power are available."

Access and conditions are a common source of delay.

9. Cancellation. "If you need to cancel or move your booking, please tell us at least [24 hours] before. Late cancellations may incur a charge."

Our guide to reducing no-shows and cancellations discusses a fair approach.

10. Aftercare. "If something doesn't seem right after we've finished, get in touch and we will put it right."

State any guarantee you provide, and for how long, in words you're confident you can honour. Some countries give customers rights that you can't reduce, so check the official guidance and don't promise less than the law gives.

Ten lines. A page at most. That covers most small jobs.

Where to put them so people actually see them

Writing the lines is half the job. The other half is making sure customers see them before they agree.

Put them on the quote. A short "Terms" section at the bottom is better than a separate document. The customer sees them when deciding.

Mention the key ones in your message. When you send the quote, highlight one or two: "Please note the price doesn't include making good decoration, and there's a 24-hour cancellation notice."

Repeat them in the booking confirmation. Dates, payment and cancellation are worth restating.

Show them on your website. A page of terms builds trust and gives you a place to point.

Keep the wording identical each time. Consistency helps both of you remember what was agreed.

Get an acceptance. A reply of "Yes, happy to go ahead" to a message containing the terms is evidence the customer saw them. For bigger jobs, a signature may be better.

Our guide to writing quotes that win more trade jobs shows how to present terms clearly without putting people off.

Some job-management tools let you save terms and include them on every quote or invoice automatically. Features and plans differ, so check with each provider and test what the customer sees. If you use a spreadsheet or word processor, a saved template does the same.

Writing in the way people talk

The aim is to be understood, so write like a human.

Use short sentences. One idea per sentence.

Use "we" and "you". "We will" and "you will" are clearer than "the Contractor" and "the Client".

Avoid jargon. If you use a trade term, explain it.

Be specific. "Within 7 days" is better than "promptly".

Be positive where you can. "Please tell us at least 24 hours before if you need to cancel" feels kinder than "Cancellations within 24 hours will be charged."

Read it aloud. If it sounds like a robot, rewrite it.

Ask a friend. Show it to someone outside your trade. If they find something confusing, so will customers.

A well-written line might look like this:

"If we find something unexpected when we start, such as damaged pipework behind a wall, we'll show you and explain the options before doing any extra work."

That is warm, clear and protective all at once.

Notice that none of the examples uses capital-letter shouting or long chains of legal phrases. They don't need to.

What a handshake can and can't do

Many trades pride themselves on dealing with a handshake. There is something good in trusting people and being trusted.

But a handshake has limits. It can't record details. It can't settle what each person remembers differently. It doesn't help if the person who shook hands isn't the person dealing with the invoice. It doesn't show anything to a third party if there's a dispute.

Writing doesn't replace trust. It supports it. A written note says "I take this seriously, and I want us both to be clear."

Most customers feel reassured, not offended, by clear terms. They've often had bad experiences themselves and appreciate a professional approach.

If you think writing things down will offend your regular customers, try framing it as helpful. "Just so we're both clear, I've put the details in an email." Few people mind that.

The most useful moment for clarity is before the work starts. After a disagreement, writing things down can feel defensive. Before, it feels thorough.

When a job is too big for ten lines

Ten plain lines suit small jobs. As work grows, so do the risks.

Consider more formal advice when:

The value is significant. There's no fixed threshold, but if a problem would seriously hurt your business, take advice.

The job is long or complex. Many stages, many trades, dependencies.

It affects the structure or safety of a building. Specific rules and regulations may apply.

It involves regulated work. Some trades have required certifications, notifications or standards.

Consumers have special protections. In many countries, domestic customers have rights that can't be waived, and specific rules about cancellation, deposits and contracts made at the customer's home or online. Check the official guidance.

You're working for a business or a larger contractor. They may have their own terms. Read them before accepting.

Something unusual is involved. Unusual risks, access, or customer demands.

For these, consider using a standard contract produced by a recognised trade body, or ask a solicitor to prepare a template you can adapt. Many trade associations provide model terms for members.

A few hours of professional help at the start can save far more later. It's like insurance: you hope never to use it, and you're glad it's there.

Tell customers when the job is large enough to need a proper contract. It signals seriousness.

A quick example, start to finish

Here's a hypothetical example to show how the lines come together.

A customer, Sam, wants a new outside tap fitted.

Alex sends a quote:

"Hi Sam, thanks for your enquiry. Here's the quote for fitting a new outside tap.

What we'll do: supply and fit one outside tap on the rear wall, connect to the existing supply and test for leaks.

Not included: making good brickwork or decoration.

Price: $X, including tax.

If we find anything unexpected, we'll tell you before going ahead and agree any change in price.

Payment: due on completion, by card or bank transfer.

Date: we're planning Thursday between 9 and 11. If we need to move it, we'll tell you as early as we can.

We'll need: access to the garden and the water supply.

Cancellation: please give us at least 24 hours' notice if you need to change the date.

Aftercare: if anything doesn't seem right, get in touch and we'll put it right.

If you're happy, just reply 'yes' and we'll book you in."

That's under two hundred words. It covers the ten lines. Sam can read it in a minute.

When Sam replies "Yes, please", there's a clear record of what was agreed.

Compare that with an exchange of "Can you fit an outside tap?" "Yes, should be about $X." Nothing wrong with it, until the day when someone remembers something differently.

Keeping your terms alive

Terms aren't something you write once and forget.

Review them yearly. Check they still match how you work. Update anything that has changed.

Learn from disputes. If an argument arises, ask whether a line in your terms would have prevented it. Add or clarify.

Check the rules. Laws and guidance change. Make a point of looking occasionally, especially for consumer and payment rules.

Keep versions. Note the date of each version, and keep copies. If a customer accepted version one, you can show what version one said.

Train your team. Anyone who quotes or takes bookings should know the terms.

Apply them consistently. If you waive a term, do it deliberately. Our guide to saying no to jobs and customers covers holding boundaries kindly.

Put a yearly reminder in your diary, perhaps with your price review. Our guide to raising your prices without losing customers suggests a yearly check-up that could include your terms.

Words that sound firm but start fights

Even short terms can go wrong if the wording is harsh. A few phrases sound strong on paper and land badly with customers.

"Non-refundable." Used on a booking payment, it can feel like a trap. Say what happens instead: "If you cancel more than a week before the start, we refund the booking payment less any materials already ordered."

"At our sole discretion." It signals that rules apply to the customer but not to you. Explain what you will do and when.

"Any and all." Legal-sounding filler that adds nothing. Say what you mean.

"We accept no liability." Blanket statements like this may not be allowed in many places and can make customers nervous. Check the official guidance where you work, and describe specifically what is covered and what is not.

"Failure to pay will result in action." Vague threats feel aggressive. State the facts calmly and check what you are actually permitted to do.

Compare two versions of the same idea.

Harsh: "Cancellations within 24 hours are non-refundable and no exceptions."

Plain: "If you need to cancel within 24 hours of the booking, we may keep part of the booking payment to cover the time reserved. If there is a real emergency, just tell us."

The second protects you just as well, and leaves room for the human moment. Customers who read it feel treated as adults.

Questions customers raise about written terms

Do I need terms for every job?

For small jobs, a few clear lines on the quote are usually enough. For larger jobs, consider something more formal.

Can I copy someone else's terms?

It's not a good idea. Their terms may not fit your work or the rules where you operate. Use them for inspiration, and write your own.

Are verbal agreements valid?

In many places, they can be, but they're hard to prove. Rules vary, so check the official guidance. Writing it down is safer.

What if a customer refuses to accept my terms?

Listen to their concern. You may be able to adjust. If not, you can decline the job.

Should I get a solicitor to check?

For anything beyond simple small jobs, it's worth considering. A one-off check of your standard terms is often money well spent.

Ten lines on your most common job

Clear, plain-English terms prevent most arguments on small jobs.

Write ten lines: what you're doing, what's not included, the price, how changes work, when payment is due, what happens if it's late, when the work will happen, what you need from the customer, cancellation and aftercare. Put them on every quote. Write in the way people talk. Take advice when jobs get larger or more complex.

Your first hour is simple. Open a blank document and write your ten lines for your most common job. Read them aloud. Ask a friend to read them. Save them as a template.

The next time a customer says "I thought that was included", you'll have a gentle answer ready, and probably you won't need it.
